This survey is the first in the Nationwide Personal
Transportation Survey (NPTS) series. NPTS was designed to collect
information on all trips taken during a 24-hour period, as well as
trips of 75 or more miles one-way during the preceding 14
days. Trips made by any means of transportation were recorded,
including automobile, walking, bicycle, school bus, motorcycle, and
various modes of public transportation. A purpose code was also
assigned to each trip: earning a living, family and personal
business, educational or religious, and social and recreational.
Demographic information was collected on participants as well,
including geographic information, age, sex, race, occupation, and
employment status of household members, and whether they owned or
had access to a car.

Universe:
The civilian, noninstitutionalized population of the
United States.

Data Types:
survey data

Data Collection Notes:

It should be noted that, due to the age and
incomplete documentation of this dataset, it is in less than optimal
condition and is provided primarily to complement the later iterations
of this series that ICPSR has acquired. A number of variables have
undocumented codes and possibly invalid values and the documentation
that does exist is difficult to read. In addition, only a small
portion of the data that were originally collected are available in
this dataset, which contains only the household information and the
Travel Day Report. Questionnaire sections not included are the
detailed Automobile Record, Shopping, Travel to Work, and Overnight
Travel.

Methodology

Sample:
Multistage probability sample of housing units, drawn from
every state and the District of Columbia.
